WATER-CLOSET TANK.

SPECFCATION fcorrning` part of Letters Patent No. 688,720, datedDecember 10, 1901- Applioation tiled November 16, 1900. Serial No.36,655. (No model.)

To all whom, it may con/cern:

Be it known that we, WILLIAM S. COOPER, Jr., a citizen of the UnitedStates, and JOHN DORRICOTT, a subject of the Queen of Great Britain,both residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in later-ClosetTanks, of which the following is a specification.

Our invention relates to water-closet tanks of that class in which isemployed a siphon having a checking device located within the down-legof the apparatus; and the object of our invention'is to dispense withthe gurgling noise or sound heretofore incident to such constructions.le provide for the admission of the air into the down-leg at a pointbelow the bridge formed by the junction of the upleg anddown-leginsteadof above said bridge, as heretofore, employing an auxiliary vent belowthe bridge and above the Outlet of the downwardly-extending tube of thechecking device within the down-leg of the apparatus.

It further consists of novel details of construction, all as will behereinafter described, and particularly pointed out in the claims.

Figure 1 represents a vertical sectional view of a water-closet tankembodying our invention. Fig. 2 represents a section on line c 0c,Fig. 1. Fig. 3 represents a section On line y y, Fig. 1.

Similar numerals of reference indicate corresponding parts in thetigures.

Referring to the drawings, 1 designates the base of a tank 2, the latterhaving located therein the outlet 3, which latter has a seat 4, in thepresent instance attached to or integral therewith, for the packing orwasher 5, which is held between the flange-nut 6 and the threadedplunger-head 7, said nut 6 having a downward annular extension 8, whichis provided with t-he bars 9 therein, whereby the valve will be properlyguided in its lupward-anddownward movement.

10 designates an inner shell or wall whose lower extremity engages theplunger-head 7, the upper extremity of said shell engaging the suitableportion of the cap or casting 1l, the latter supporting the outer shell12,whose lower extremity terminates a short distance above thehoad 7,whereby itwill be seen that an up-leg 13 is formed through which watercan flow in the direction of the arrow et upwardly through the suitableports 14 in the cap 11 over the bridge 15, as indicated by the arrow b,into the down-leg 1G, which is formed by the space within the inhershell 10.

17designates a checking-tube which is provided with the ports 18, saidchecking-tube terminating at a suitable point in the lower portion ofthe down-leg 16, the upper extremity of said checking-tube beingsuitablysupported in the cap or casting 11 and communicating,by means ofthe passage 19,with the downwardly-extending pipe 20, which forms partof the checking device, whose lower extremity terminates at a suitablepoint near the bottom of the tank i.

The cap or casting 11, the up and down legs 13 and 1G, and the washer 5and its adjuncts depend from the lever 21 by means Of the connection 22common to said lever and to the eye 23 of the leg 24, projecting fromsaid cap or casting 11, said lever 21 being suitably fulcrumed.

XVe deem it important that the auxiliary vent-ports 1S be below thebridge and between the same and the lower or outlet end l of the tube17, as shown, for by this disposition of the vent the air is admittedinto the down-leg at a point below that at which the water enters saiddown-leg, and the noise caused by the mixing ofthe air and wateris notheard as itis when the mixing takes place above the bridge.

Y The operation is as follows: The operation of unseating the valve iseffected by imparting the proper movement to the lever 21, whereby thewasher 5 is raised from its seat and the water passes out through theoutlet 3. Upon releasing the lever the washer reseats, and by reason ofthe partial vacuum formed within the up-leg 13 and the downleg 16 itwill be apparent that water will dow upwardly in the up-leg 13 andthence through the port 14E into the down-legit, which operation willtake place until air is admitted to the lower extremity of the outercheckingtube 20, said air passing through the ports 18 of thechecking-tube 17 at the proper time, and thereby causing the breaking orcessation of the perfect Siphon action, while a par IOO tial siphonaction will continue until the water-level of the water in the tank isbelow the lower extremity of the tube 17, when lthe siphon action willentirely cease, the latter (a partial Siphon) constituting theafterfill.

It will be apparent from the foregoing description that we have produceda very simple and effective apparatus for the purpose named wherein wedispense with fio-ats or tripping mechanism and their adjuncts whichhave been heretofore employed in devices of this character.

Having thus described our invention, what we claim as new, and desiretosecure by Letters Patent, is-

1. In a water-closet tank, an up-leg and a down -leg and a bridge formedthereby, a checking device having an outlet below said bridge and anauxiliary vent for said checking device above said outlet and also belowsaid bridge, whereby air is admitted at the proper time into saiddown-leg, only below the bridge so that the gurgling noise is prevented.d Y

2. In a water-closet tank, an outlet therefor, a plunger, an tip-leg anda down-legami a bridge formed thereby, and a checking device consistingof a tube outside of said plunger and a tube extending downwardly insaid down-leg, the ontletot the latter being below the bridge` saiddownwardly-extending tube being provided with an auxiliary Vent aboveits outlet'and below said bridge, whereby .airv is admitted into thedown-leg below the bridge and below the 'pointof ingress of the waterand the gurgling noise prevented.

In a water-closet tank, a cap, an inner and an outer shell dependingtherefrom, and a bridge formed thereby, a checking-tube depending fromthe cap within the inner shell and having an auxiliary vent between itsends and below said bridge, an outer checking-tube extending outside theouter shell and communicating with the inner checkingtube through a portin said cap, and a plunger carried by the lower end ofthe inner shell.
